' cry, and the like, by means of which color stripes ma mechanica y. 7

The object of the invention is to provide a novel device for applying circular color stripes to flat, angular or curved surfaces, which consists of a power-driven table, by means of which the articles to be decorated are supported and rotated at suitable speeds during the striping operations.- A further object is to provide novel means for tilting and holding the waresupport at different angles, for facilitating the striping of angular surfaces. A further object is to provide a vacuum chamber, which communicates with the rotatable work-table and supplies suction, for supplementing the normal pressure of, and for holding the crockery and dishes truly concentric to the table, thereby preventing displacement or shifting of the ware due to centrifugal force caused by the rotation of the table. A further object is to provide a gauge by which the ware-supporting table may be set and held at the proper angles for effecting the striping of curved and angular surfaces. A further object is to provide a gravitative metal brush or tool of novel construction for applying the colors for decorating theware; the said tool being arranged to bear lightly on the work, and being hinged for automatically applying stripes at difi'erent levels. A further object is to provide a novel support for the brush, com rising a number of connecting and co-actmg-parts, which are arranged for universal movements relatively to the work-table. as well as to each other, and by means of which the striping pen may be raised, lowered and moved laterally relatively to the rotating table and the ware.

. And a further object is to provide mechanical means for supporting and rotating, and also for striping crockery and other articles,-

which allows the operators the free use of their hands for adjusting and attending the machines, renders the more accube applied to various wares.

rately and readily effected, and besides facilitates quantity production at greatly reduced cost.

. I attain these objects bythe means set" forth in the detailed description which fol lows, and. as illustrated by the accompanying drawings, in which- I Figure 1 is a partial side elevation and partial vertical section of the complete apparatus.- Fig. 2 is anend elevation of the forked holder which supports the striping tool. Fig. 3 is a top-plan view of the holder and tool. Fig; 4 is a front side elevation of the apparatus shown in Fig. 1. Fig. 5 is a front elevation of the device; showing by full and dotted lines the manner of-inclining the work-supporting table for performisa'horizontal section, taken on line' 10 -10 of Fig. 1.

In the drawings, 2 represents a pedestal, having. an enlarged foot-flange 2' at 'its' lower end, and a fork comprising arms 2 at its top end. The free ends of the arms 2 are formed with pillow-blocks 2, which with caps 2 constitute alining. bearings 2, for rotatably supporting a hollow cylindrical body 3, Whose interior comprises a vacuum chamber 3 the body 3. having oppositely facing gudgeons 3*, which are journaled in the bearingsQ". .The journals 3 are bored axially to receive .a shaft 4, which passes through the body 3 and rotates in. the said journals. Inside the chamber 3' the shaft 4 is fitted with a bevel pinion 5 which drives a larger bevel-gear. 5' and'on one outer end of said shaft is mounted a sheave 4, which may be driven by a motor or other suitable power I (not shown), by means of a belt 4*. At the opposite end of shaft 4, an anchor-like gauge 6 is concentrically mounted on the outer end of the corresponding journal 3, by screws 6'. The gauge 6 is provided with a number of reguplain holes 6, to receive a screw 6, WhlCh is threaded into the adjacent arm 2, as at 6", for holding. the body'3 in the various adjusted positions, as shownin Figs. 4 and 5. The open bottom of the body 3 is sealed by a plate 3, The vacuum in cham- 8* is rigid on shaft 7, by a pin 7'. The top end 8 of the support 8 comprises the lower member of another ball-bearing, the upper member thereof consisting of a ring 9, between which and the member 8, balls 9 are disposed. The two ball-bearings are adjustable relatively to each other and proper spacing and tension of the parts may be effected, by means of a ring 9, which is pinned to shaft 7, andrscrews 9 which are threaded into the ring 9, as shown in Figs. 1, 4, and 5. Upon the top end of shaft 7 is rigidly mounted the circular work table or platform 10, which supports the articles, as 12, to be decorated or striped. The parts 3,

6, 8, and 10 are all swingable on the pivot 4,

as onepart, for tilting the table 10 in opposite directions, as shown in Fig. 5, preferably for bringing angular or curved surfaces, as 12', of the ware, substantially to the horizontal plane during the striping operations.

The table 10 is arranged to be constantly I rotated, preferably at a speed low enough to prevent the displacement or shifting of the ware 12 fro its proper position (concentric to shaft 7) and the consequent distorting of the circular stripes 12 which must also be concentric to the common axis of the shaft 7 and the ware 12, as best seen in Fig. practice,the safe speed of the table 10 usually falls between 15 and 25 revolutions per minute; To further insure the positive holding of the ware 12 concentric to the table 10, I make use of the vacuum, and for this purpose, the shaft 7 is hollow throughout, thus providing a free passage 7 which extends from the top surface of the table 10, to the bottom side of the gear 5'. By this arrangement, a strong suction is exerted between the meeting faces of the table 10 and the ware 12, for assisting grav ity to hold the ware in place. Ordinarily, when the table 10 is being operated horizontally, as shown in Figs. 1 and 4, the ware 12, unless exceptionally light, will retain its proper position without the vacuum; but the vacuum is preferably emplo ed whenever the table is operated at inclinations as shown in Fig. 5. The line w intermediate the body 3 and the table 10, represents the level of the usual factory work-bench, which in the present showing serves as the principal support for the striping 1 mechanism, which will now be described in detail:

a 13 represents a normally upright standard, preferably a tube, which is adjustably supported by a bracket 13, the latter being secured to the bench m by screws 13. The bracket 13 is provided with a ball-andsocket arrangement, indicated at 13, by means of which the standard may be inclined at different angles to the vertical, as shown by dotted lines in Fig. 1. The standard may be held rigid in any desired position relatively to the bracket by clamping bolts 13. The standard is fitted with a clamp 14, which is controlled by a screw 14', having a circular handle 14 This clamp may be moved along as well as around the so standard, in a well-known manner. One member of the clamp 14 pivotally supports a sleeve 14. in which a rod or tube 15 isslidably and rotatably mounted, and the said rod may be held rigid after adjust- 35 ments, by means of a screw 14. The forward end of the rod 15 is formed with a perforated lug 15", which is pivotally disposed between perforated lugs 16' -of a forked member 16, whereby the said member may be raised or lowered without disturbing the adjustment of the rod. The parts 15'16' are arranged to be held when adjusted, by a thumb-screw 15. The arms of the member 16 are bored correspondingly, to receive a shaft or rod 17, both ends of the latter preferably extending beyond the said arms, to provide a considerable range of endwise adjustment of the shaft. 18 represents a lever or part, which is rigidly mounted on the shaft 17, between the arms of the fork 16, by which the shaft may be moved lengthwise. Near its free end the lever 18 is perforated to receive the plain end of a screw 19, the said screw eing swiveled in the lever, by means of a pin 18'. The screw 19 extends outwardly through a threaded hole in one arm of the member 16, and its outer end has aknurled head 19' for manipulating the screw. The full and dotted ines in Figs. 3, 4, and 6, show the manner of adjusting the shaft 17, by the rotation of screw 19. At the opposite sides of the other arm of member 16, the shaft 17 is fitted withadjustable stop-collars 17 by which the longitudinal movements of the shaft may be regulated and limited; the sazid 'collars being held in place by screws 1 The striping brush or pen, comprises a relatively thin fiat body portion 20, from one end of which extends, preferably at a down wardly pointing angle, a reduced tapering ruling or striping portion 20'. This tapering portion 1s preferably formed as best seen in Figs. 8 and 9, by folding the lateral edges 20", of a relatively sharp V-shaped sheet of metal towards each other, for providing a gradually downwardly diminishing trough 20, wh ch is filled with the liquid or semi liquid coloring matter, by which the f decorative striping is effected. The portion holds a. considerable quantity of the coloring liquid, and' feeds it, fountain-like,

; to-the surface, by asteady gravitative flow. An important feature ofthe striping brush 20' consists inkeeping the facing edgesof the folds 20 separated throughout their length. By this construction and arrange-- ment, the flow of the color matter is con-. tinuous andsteady, and inspection and 619%}1'1- 1e .breadths of the stripes, as12,-are usually.

ing of 'the brush are facilitated.

controlled: bythe degree of bluntn'ess of the extreme tip 20' of the striper.- A stripe may be broadened, when made by a relatively sharp tip, by adjusting the brush laterally, by means of the screw 19 (see Fig. 6). This method is usually followed when both light face of the section 21 of the holder, and is removably heldlin place by a handle 21,

- one end of the handle being threaded, passes through a hole in the body 20, and .screws into a threaded 7 socket of the member 21 (see Figs. '1 and 7). The member 21 is perforated to receive the shaft 17, upon which it isslidable, as well as rotatable, for

suitably adjusting the holder and tool independently o'f the'part '16 and its pivot 15*.

The holder 21 may beheld rigid to the shaft 7 7 10 is operated atthe proper speeds. By this construction and arrangement, the pressure of the brush 20 upon the ware is always the same, during the striping operations, and may be increased or decreased according to the position of the holder 21-21' relatively to the shaft 17. That is to say, if the holder is disposed at a considerable incline, the pressure at the tip 20' of the brush will be increased, due to the shifting of the center of gravity of the handle 21, in a well-known manner.
